Hi there. Yes.
The issue I encountered was caused by the bad Internet connection between the access point and HPE's activation server. During the initial setup, it will downloads the latest firmware automatically from the server, so the site is not up until the update process is finished.
My solution is: sent a unit to the reseller and bring it up by their already activated devices, then get it back and power on all units, so they will be activated by the previous one.
